The Venus Fly Trap: Like the Sundew, it makes itself very attractive, oozing nectar across the brim of each leaf; but any visiting insect had better watch out for these six tiny hairs. This fly has to tread carefully. If it strikes one hair, it can carry on feeding, but a timer has been set. A second strike in less than twenty seconds and the fly is doomed. An electrical impulse is triggered and the leaf snaps shut in just a fraction of a second; the tips lock together like prison bars. If the fly is very big or very small, it may just manage to escape. But most are trapped - and die. (x)
